The performance and longevity of advanced battery systems, particularly lithium metal and sodium-metal batteries, are critically dependent on the stability of the interfaces between the electrodes and the electrolyte. Electrolyte additives play a pivotal role in engineering these interfaces, and 1,3,6-hexanetricarbonitrile (HTCN) has emerged as a highly effective solution. NINGBO INNO PHARMCHEM CO.,LTD. is a key supplier of this essential compound, understanding the intricate mechanisms through which it enhances battery stability.

At the heart of HTCN's effectiveness lies its multi-functional nitrile chemistry. In lithium metal batteries, the primary challenge is to form a robust solid electrolyte interphase (SEI) on the lithium metal anode. An ideal SEI layer should possess high ionic conductivity for efficient lithium ion transport while being electronically insulating to prevent continuous electrolyte decomposition. 1,3,6-hexanetricarbonitrile aids in the formation of such a layer by undergoing reductive decomposition at the anode surface. This process leads to the generation of beneficial species, such as lithium nitride (Li3N) and lithium carbonate-like species, which contribute to the SEI's structural integrity and ion transport properties.

NINGBO INNO PHARMCHEM CO.,LTD. provides 1,3,6-hexanetricarbonitrile, which also plays a significant role in stabilizing the cathode electrolyte interphase (CEI) in high-voltage lithium-ion batteries. For cathodes like nickel-rich layered oxides, which are prone to electrolyte attack and metal ion dissolution at high potentials, a protective CEI is crucial. HTCN, through its electrochemical activity, can form a passivation layer on the cathode surface. This layer effectively shields the cathode material from direct contact with aggressive electrolyte components and prevents the leaching of transition metal ions, thus preserving the cathode's structure and capacity over prolonged cycling. This mechanism directly contributes to the goal of improving battery cycle life and performance.

The molecular structure of 1,3,6-hexanetricarbonitrile, with its three nitrile groups spaced along a flexible carbon chain, is key to its function. This structure allows for preferential adsorption and electrochemical reactions at both the anode and cathode interfaces. Theoretical calculations and experimental observations confirm that HTCN is more easily reduced at the anode and oxidized at the cathode, allowing it to act as a dedicated interface modifier.
